Answer:
Before the plank will tip cat will walk 1.652 m
Explanation:
Mass of the cat along with plank
Center of mass of the plank
Mass of cat
We have to find how far right of sawhorse B.
Plank will tip when weight of the cat about B is greater than the torque by the weight of the plank.
Balancing the the torque
<span>Each light in the string will get dimmer. Let us look at what is causing this.
The scenario provided is that of a Series circuit.
In the case of a series circuit, the current flowing through each of the load (String of bulbs in our example) is same, while the voltage drops equally across all the bulbs (provided all the bulbs are of the same rating)
For example if we have a 230 V AC supply, and we have connected 10 bulbs in series, the voltage across each of the bulbs is (230/10=23 V). As you can see, if you add more bulbs, the voltage at each bulb drops further, causing them to dim.
Hence, each light in the string will get dimmer as you add more lights. Option (B) is the answer.</span>
Nonmetals often share or gain
electrons. The nonmetals in the periodic table increases as you move to the
right and decreases as you go down. This is because, the smaller the atom, the
reactive it gets due to less electron attached to the orbits of the atom. The
reactivity of nonmetals is arranged in decreasing order.

Answer:
It is safer to endure an explosion on land rather than in water. So it is better to take cover on lanad.
